How is the temperature of a blackbody related to its color?

The color black is known to absorb the most heat, which makes it one of the hottest colors. It is the hottest because it only absorbs the light and doesn't reflect it back unlike other colors.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
